BMW Radiators for BMW Z3 (1996-2002)

Clear BMW chassis

We sell only OE supplier or approved aftermarket upgrade radiators for your BMW. It seems BMW took some shortcuts when it came to radiator design and used weak materials like plastic for critical connection points. If you are tracking older models like E30, E36, or E46, you probably are well aware of these issues. As these cars age, the plastic pieces become more brittle and failure prone. The solution is to replace with upgraded radiators that perform as upgrades for the original, failure prone radiator to avoid being left on the side of the road or, worse yet, the track.

Behr Replacement Radiator - More than likely, you are going to replace the radiator in your vehicle at least once. The joints where the cores meet the end tanks tend to get weak and are the first place to spring a leak. Impacts to the fins themselves can cause holes to form. Corrosion and clogging from the inside can make cooling less than effective and compromise coolant flow.
